The purpose for the fan is to cool the radiator, therefore, the blades would, by definition, turn TOWARD the direction that the part of the blade that is closest to the engine... Therefore, it would push the air toward the radiator, particularly, when the truck is not in operation. As the previous poster indicated, it is generally clockwise.
At the front closest to the radiator
# 1 cylinder is at the front by the radiator on the Ford 300 cubic inch straight 6 cylinder
On your 4.9 liter / 300 cubic inch straight six cylinder engine # 1 cylinder is at the front of the engine nearest the radiator
On the Ford 200 cubic inch straight 6 cylinder engine , the distributor rotor turns CLOCKWISE
A cylinder has no straight edges
Ford V8 engine - COUNTERCLOCKWISE Ford straight 6 cylinder engine - CLOCKWISE
would be the 1st one closet to the radiator ======================================================= On a straight ( inline ) 6 cylinder , the Ford V6 with rear wheel drive / 4X4 is : firewall 3 - 6 2 - 5 1 - 4 front
Fords 4.9 liter straight 6 cylinder is 300 cubic inches , what is your question ?
NORTHAmended answerLight travels in straight lines.
The wave velocity vector is parallel to the cross product of the electric and magnetic vectors.If you crank a wood screw from the Electric-field direction to the Magnetic-field direction, the screw proceedsinto the wood in the direction of the wave's velocity vector.Here's another advanced and highly technical way to keep these directions straight ...Curl the fingers of your right hand in the direction FROM the electric vector TO the magnetic vector.Your right thumb (when extended) points in the direction of the waves velocity vector, and alsothe "Poynting Vector"; that's the direction in which the wave carries energy.
The engine drain plug for 6 cylinder is on the lower left side of engine block.
He is definitely straight - as is one direction.
